TUBULAR-/VTCK BURNER.

Application filed July 12,

To ZZ whom if may concern:

Be it known that I, JOHN Cnrrnnnon, citizen of the United States, residing at Attleboro Falls, in the county of Bristol and I State of Massachusetts, have invented certain new and useful Improvements in TubularWick Burners, of which the following is a specification.

This invention relates to improvements in tubular-wick oil-burners and more particularly to the tubular sleeve member which embraces and carries the tubular wick; and the object of this invention. is to provide simple and effective means in a burner of this character for attaching the wick to its carrier whereby a movement of the carrier by rotating the feed gears, will serve to positively move the wick a corresponding distance. Y further object of the invent-ion is to provide a tubular carrier with a pair of in tegral prongs cut from the stock and turned inwardly to extend through the wick fabric and be clinched on the inner side thereof.

wWith these and other obiects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a sectional side elevation showing a portion of the oil fount with my iinproved wick-carrier operatively mounted therein and partly broken away to better 35 illustrate its structure.

Figure 2 is a sectional end view showing the adjusting gear in mesh with the openings in the carrier tube, also as being sectioned through the wick-engaging prongs.

Figure 3 is an enlarged fragmental view showing the prongs as cut from the stock of the outer sleeve or wick-carrier and turned slightly inwardly to engage the fabric of the wick.

Figure 4. is the same as Figure 3, and showing the prongs as turned squarely inufardly.

Figure 5 shows the ends of the prongs as folded toward each other and clinched 50 around a section of the fabric. Ordinarily the wick carrier tube is connected permanently to the wick by means of rivets, but it is found in practice that this is more or less expensive as itl requires several opera- 55 tions, such as punching, inserting and subplace into its carrier and then cutting or punching portions of the stock o-f the tube and turning these cut portions inwardly providing piercing prongs which pass through the fabric, and then fold the ends of these prongs to clinch them over the inner face of s the fabric, all of which is done by the simple operation of cutting and punching with cutting and bending tools, thereby firmly attaching the tube to the wick; and the following is a detailed description of one means by which this result may be accomplished W ith reference to the drawings, 10 designates the body portion of the oil-carrying fount into which the wick supporting collar 11 is threaded as at- 12 and in this collar 11 is slidably mounted the tubular-wick carrier 13, which carrier is of a size to receive the wick 14 and just fit nicely around the same. The upper edge of this carrier is usually provided with a multiplicity of inturned prongs 15 which imbed themselves into the outer surface of the wick to assist in causing` the wick to move with the carrier, but it is found in practice that these prongs are not sufficient in all cases to prevent the wick from slipping and that, therefore, it is necessary to more firmly secure the wick so that it cannot slip when the carrier is adjusted by the rotation of the adjusting gears 16 through its operating handle 17 connected to the outer end of the gear shaft 18. The teeth of this gear or pairy of gears are arranged to enter any of the rows of vertically-disposed perforations or openings 19 in this sleeve. Therefore, in order to effect a permanent and binding connection between the carrier sleeve and the wick, i first insert the wick into the carrier and then place the same onto a suitably-shaped anvil and pierce, cut or punch small sections of the stock of the sleeve as at Q0, preferably having pointed ends arranged to form a pair of cooperating prongs 21, and l bend these cut portions or prongs inwardly, as illustrated in Figures 3 and 4t, into staple form which, as they are turned to sweep inwardly from the surface of the sleeve, gather that portion of the threads of the fabric 22 which is within their sweep. These inwardly-exq tending` endsare then preferably folded towards each other, as illustrated in Figure 5, the inner surface 23 of these prongs being substantially flush with the inner surface 24 of the wick. VThe sleeve with its wick is then positioned over they inner or wick-tube 25 and these clinching members serve as bearings about the sleeve to support it against the working thrust of the operating` gears 16, to prevent the sleeve from compressing` the wick whensubjected to a .severe Working. strain of the gears upon the vsleeve particularly when the sleeve is m its raised` position.

ly my improved method of securingr the sleeve permanently to the wick, it is only` necessary-to first place the wirk into the sleeveand then place the whole into the inachinewhich first forms the pro'ngs, then earries themimvardly through the wick fabric and subsequently clinches them on the inside thereof thuspermanently securing the sleeve `tothe wick Without necessitating the handling of small, separate parts such as rivets and the like, and without punching spez-iai holesV for the reception of the` rivets and without the `,operation of spreading the l rivet ends after the rivet has been posig sleeve to the Wick is extremely simple Y tioned.

By my improved method the stoel; of the sleeve itself is employed for forming` the prongs.

My improved means for connecting' the and practical and elfective in its operation.

their end portions imbedded intothe innen surface ot the wick substantially flush therewith to bind the wiclr to the sleeve and also serve as a spacer to support the wirk against compression when the sleeve is acted upon by the operatingr mechanism.

2. ln a wick-carryingv sleeve, substantially triangularly-shaped prongs cut from the body of the wick-sleeve and folded inwardl)v to pierce the wick, the pointed ends` of said prongsbeing` turned inwardly toward each `other to embrace a portion lof the wich, the

end portions of said prongs beinpr imbedded into the wick Hush with the inner surtave thereof to bind the wick against the` bod),7 of the sleeve. said inturned prongs also serving` as spacers to support the wich against compression and provide metallic slides for the sleeve when moved by they operating mechanism.

In testimoniv whereof I ailix my signature.
